With the Galaxy High celebrating the Christmas holidays, Principal Kirkpatrick is angry because Josh played a prank with putting all of his pictures in one box. For punishment he sends Josh to patrol with Yoko and Brett. When Josh, Yoko and Brett take a wrong turn on a routine patrol and suddenly find themselves lost in unfamiliar space territory, they're quickly ambushed and captured by an IAC-an Intergalactic Alien Catcher. And, before they know what hit them, they're locked up in the cosmic version of a dog pound (along with a bevy of other funky alien creatures)! But that's the least of their worries. Yoko, because she's so "colorful" and "entertaining," is almost immediately "adopted" by a rich, bratty alien kid who views her as a plaything! She takes her to her tricked-out space mansion and commands her to entertain her (and, being a spoiled brat, she's not that easily entertained). It's up to Brett and Josh to escape the pound and save Yoko before the rough-housing alien runt breaks her like she does all his other toys!!! In a b-story, the Galaxy High gang celebrates the Christmas holidays... space-style.
